removeWhere method Null safety

  1. @override
void removeWhere(
  1. bool test(
    1. Node
    )
)
override

Removes all objects from this list that satisfy test.

An object o satisfies test if test(o) is true.

var numbers = ['one', 'two', 'three', 'four'];
numbers.removeWhere((item) => item.length == 3);
numbers.join(', '); // 'three, four'

The list must be growable.

Implementation

@override
void removeWhere(bool Function(Node) test) {
  for (var node in where(test)) {
    node.parentNode = null;
  }
  super.removeWhere(test);
}
